There are various types of I/O available in the VCD 723. The terminal I/O
specifications are listed in Table 2. The digital feedback tachometer connector
specifications are listed in Table 3. A diagram of these connections can be found
in Figure 4.

The input is off (logic 0) when the input is open, and on
(logic 1) when the input is connected to Logic Input
Common (0V). If input is from a relay contact, the
contact rating must be: 30 VDC min
100 mA min
If input is from an open collector, the rating must be:
35 VDC min
100 mA min
This is always used for external fault generation. This
input cannot be reassigned. The SN12 constant can be
used to set this input to Normally Open or Normally
Closed. If Normally Open is selected, a fault is indicated
when the contact closes and if Normally Closed is
selected an open contact indicates the fault.
Normally open relay contact.
Contact capacity: 250 VAC at 1A or below.
30 VDC at 1A or below.
Common (0V) for use in wiring Logic Inputs.
Shield sheath tie point which is connected to Chassis
Common.
Non-isolated 0 to 10 VDC analog input. Input has 20K
ohms of impedance. Resolution is 10 bits.
Non-isolated 4 to 20 mA analog input. Input has 250
ohms of impedance. Resolution is 10 bits.
Control power supply for analog input: +15 VDC at 20
mA max.
Non-isolated 0 to 10 VDC analog input. Input has 20K
ohms of impedance. Resolution is 10 bits.
Common (0V) for use in wiring analog inputs.
18 is Normally Open, 19 is Normally Closed, and 20 is
Common. Contact Capacity: 250 VAC at 1A or below.
30 VDC at 1A or below.
Non-isolated 0 to 11 VDC analog output. Maximum
sourcing current is 2 mA. 21 is positive with respect to
22. Resolution is 8 bits.
Non-isolated analog output. Approximately 5 VDC at
rated output current.
Photocoupler isolated output. Capacity of +48 VDC
max at 50 mA max.
Common (0V) for use in wiring multi-function open
collector outputs.
